Yes ... I've seen many such devices, Bill. In fact, as it happens, I'm looking at one right now! It's called a PC.

OK. So, what's the answer? Hint:- think isolation transformers, and having the kit mounted on a decent trolley or cart ("medical grade", if you like that terminology).
By the way, what is the set-up you're referring to? That is, where is this "device" expected to sit? How far away from the "patient zone"? What is it (electrically) connected to, and stuff like that?
I guess that
this answers most of my questions! Notice that thing sitting in the guy's ear - now, that really
is an ... er,
device! But, where is the PC "box" (actually built-in to the display? ... must basically be laptop technology, then, I would have thought). After all, surely there must a hard-drive somewhere. And, most importantly of course, where is the power supply? A SMPS
brick ... or again, built into the display?
I believe that this could be a case where a Risk Assessment may actually be useful. Which is the greater risk to the patient ... that posed by extraneous leakage currents, or administration of incorrect drugs
etc. (the sort of think I imagine this system is aimed at eliminating)?
Safer Sleep ... has provided peri-operative safety solutions to the healthcare industry in New Zealand since 1999.
In 2008 the Company installed six systems into two sites in the United Kingdom. The sites, Papworth and Wrexham Hospitals are participating in a national trial into anaesthesia drug safety practices.
By the way, I would be interested to hear what the Rep is saying (nothing, most likely), plus what the company's literature says in this regard (ditto), and also what markings (if any) appear on the kit in question.
